Yes, thought so,but that's good because i'll give you an accurate report on the common DA zooms that plenty of people own or have discarded.Starting with the widest.
The DA 16-45mm(that I own) is usable right through the focal length, indoors, outdoors and probably on the moon( but I cant confirm that!)
The DAL wr 18-55 vignettes from 18-24mm, after that its fine.
The DAL 50-200 wr usable right though the range.
The DA 55-300 same as 50/200
The DA 18-135 vignettes all the way, which is a shame.
AS you know the 40mm ltd and 50mm plastic fantastic work well too
So lots of asp/c shooters would have these or some of these, they work and with the bigger sensor I LIKE what I'm seeing.
Also,the vivitar/tamron AF 1.4x TC, works right thru the range on the 55-300mm( extends AF to 420)
Other AF lenses ive tested and found good are the F35-70(2nd favourite on K-01) and the FA 80-320 AF hunter, terrible past 200mm on K-01, hunts at longest end on K50, but is usable on the K1(without the TC).Amazing what a bigger sensor can do for a lens.
Originally posted by ChristianRock I have the 16-45 and I have FF Pentax cameras (film). And based on what I see in my viewfinder, I know you must be confused.
Well, I thnk you should get your eyes tested OR test it on a K1, because that's what ive tested mine on.
